Mediafire.
Mediafire is very fast.
Rapidshare, hotfile, are troublesome.
Because they have limitations and also they check your IP. This
may be a problem if your ISP has the ISP proxy, like Starhub. So in
this case you will never get the chance.
Mediafire does not check IP, does not limit ur speed, and you
can use any download accelerator programs on it.
To search, usually do something like this,
For instance, you are looking for Avatar.
"Avatar mediafire"
Search that in google.
or like this,
"Avatar mediafire dvdrip"
Something like that.
